The direction this game takes is worrying. In this post I am speaking from a support player standpoint and while I do understand that people do not enjoy endless stalemate fights I agree with the removal of magi amulet. This way firebrands can add more pressure to each other in order to force cooldowns and it also cuts overall sustain. BUT there is no point in playing support when people legit get oneshot. The burst damage has to be nerfed significantly. It is not fun to die with all cooldowns up when you don't even get to use them. Teamfights should be decided by cooldown management, swapping targets, coordination and communication and not by oneshotting people. If you are gonna kill the support role this will also kill the viability of any class that relies on support like necro and partially revenant, too. Right now I feel like I can not keep up with the support vs power classes, people just die in the cast time of a single heal and besides heal firebrand offers nothing, no damage, no 1v1 potential, no snowball potential, no mobility, no 1v2 potential to stall. The support role has already died in the ranked gamemode and even in tournaments like the last monthly subpar 5-dps setups made it into the finals of both Na and EU monthly. While the proposed changes already adress warrior and holo dps changes you are not planing to touch mesmer and thief, the most broken classes in the game. To visualize what I am talking about I will just give you examples of how stupid power damage in the current meta is:
https://clips.twitch.tv/AcceptableBlazingPeppermintWow medium armor + vitality amulet getting clean oneshot from stealth by a single mesmer.
https://clips.twitch.tv/TangentialFrozenAdminUWot s/d thief dealing ~23k damage and removing 2x aegis in 3-4 seconds on heavy armor target 1v1 no might stacks. I was at 100% hp + aegis when I started casting sanctuary. Feel free to pause the clip at the point where I start casting sanctuary and rewatch it carefully. I also got hit 5x inside my sanctuary (fix pls). Now Imagine a second mesmer/holo hits you aswell, there is no way to heal/kite that. A class that offers nothing but heal atleast needs to be able to survive a single player, yet more firebrand nerfs are planned but no thief damage nerfs.
https://clips.twitch.tv/ProudIntelligentPlumPhilosoraptor another top player (he is using a toughnes amulet) being skillfully outplayed by stupid class, good luck supporting through that.
https://clips.twitch.tv/InexpensiveSilkyHyenaPupper I landed a couple of oneshots myself as core guardian, then this happened xD The game turns into a clown fiesta.
When ele and core guardian do burst people on 30 second cooldowns without extraordinary disengage ability the risk/reward may be justified, but for mesmer and thief who can spam this kind of damage while being able to reliably disengage from overcommitment it is not acceptable + mes/thief also can use this mobility for decaps and +1s which guard/ele cant and mesmer has access to the strongest and unique utility in the game that has no counterplay to it (portal).
